Cholumikizira cha waveguide loop ndi chipangizo cha microwave chokhala ndi waveguide ya loop ndi mizere iwiri yotumizira.

Cholumikizira cha microwave cholunjika chimodzi ichi chimagwiritsidwa ntchito makamaka polumikiza bandpass filter ndi short-circuit impedance pa mizere yotumizira. Cholumikizira ichi chimatha kusamutsa mphamvu yamagetsi apamwamba kuchokera ku mzere umodzi wotumizira kupita ku wina, motero zimapangitsa kuti kuwala kulumikizane.

Mfundo yogwirira ntchito ya waveguide loop coupler imadalira kwambiri mbali ziwiri: makhalidwe a transmission a loop coupler ndi microstrip line. Directional coupler imatanthauza power divider yokhala ndi directionality.

Cholumikizira cha loop ndi gawo lofunika kwambiri mu zolumikizira za waveguide loop, zomwe makamaka zimagwira ntchito yolumikizira mphamvu.

Kulumikizana kwa annular kumeneku kumakhala ndi ma loops awiri oyandikana, ndipo theka la loop limodzi limakhala ngati doko lolowera ndipo theka lina limakhala ngati doko lotulutsira. Chizindikiro cha ma frequency apamwamba chikafika pa annular coupling motsatira doko lolowera, chidzatumizidwa ku theka la loop loyandikana nalo. Pa nthawiyi, chifukwa cha kukhalapo kwa mphamvu ya maginito, chizindikirocho chidzatumizidwanso ku theka lina la loop, motero kukwaniritsa kulumikizana kwa mphamvu. Pomaliza pake, n'zotheka kuphatikiza chizindikiro cholowera kuchokera ku doko lolowera kupita ku doko lotulutsira pamene mukugwiritsa ntchito mphamvu zambiri zolumikizira.

Zizindikiro zazikulu za magwiridwe antchito a ma couplers a broadband single directional loop

Zizindikiro zazikulu za magwiridwe antchito a ma measuloop directional couplers ndi monga operating frequency range, coupling degree (kapena transition attenuation), directionality, ndi input/output standing wave ratio.
1. Mlingo wolumikizira umatanthauza chiŵerengero cha decibel cha mphamvu yolowera ya main waveguide ku mphamvu yotulutsa ya coupling port pansi pa mkhalidwe wofanana ndi katundu pa doko lililonse.
2. Kulunjika kumatanthauza chiŵerengero cha decibel cha mphamvu yotulutsa ya doko lolumikizira ku mphamvu yotulutsa ya doko lodzipatula pansi pa mkhalidwe wofanana ndi katundu pa doko lililonse. Zolumikizira zolunjika zimagwiritsidwa ntchito kwambiri poyesa zizindikiro pakugawa mphamvu ndi kuyeza ma microwave.

Qualwaveimapereka ma coupler a broadband ndi ma single directional loop amphamvu kwambiri kuyambira 2.6 mpaka 18GHz. Ma coupler amagwiritsidwa ntchito kwambiri m'njira zambiri.
